The OSD signal may include various data such as a User Interface (UI), a variety of menus, widgets, icons, etc.

The OSD generator 340 may generate a signal for displaying broadcast information based on a caption or EPG of a broadcast image.

The OSD generator 340 generates an OSD signal or a graphic signal and thus may be referred to as a graphics processing unit.

The mixer 350 may mix the decoded video signal processed by the video processor 320 with the OSD signal generated by the OSD generator 340. The mixed signal is provided to the formatter 360. By mixing the decoded broadcast image signal or the external input signal and the OSD signal, the OSD may be overlaid and displayed on the broadcast image or the OSD or the external input image.

The FRC 355 may change the frame rate of an input image. The FRC 355 may maintain the frame rate of the input image without frame rate conversion.

The formatter 360 changes the signal output from the FRC 355 to be suitable for the display 180. For example, the formatter 360 may convert a received signal into an RGB data signal and output the RGB data signal. The RGB data signal may be output in the form of a Low Voltage Differential Signal (LVDS) or mini-LVDS.

The formatter 360 may change the format of a 3D video signal or convert a 2D video signal into a 3D video signal.

The audio processor (not shown) of the controller 170 may also adjust the bass, treble or volume of the audio signal.

The data processor (not shown) of the controller 170 may process the demultiplexed data signal. For example, if the demultiplexed data signal was encoded, the data processor may decode the data signal. The encoded data signal may be Electronic Program Guide (EPG) information including broadcasting information such as the start time and end time of broadcast programs of each channel.

The block diagram of the controller 170 shown in FIG. 3 is exemplary. The components of the block diagrams may be integrated or omitted, or a new component may be added according to the specifications of the controller 170.

In particular, the FRC 355 and the formatter 360 may be included separately from the controller 170.

FIGS. 4 to 5 are diagrams showing various examples of a platform structure in the image display apparatus of FIG. 2.

The platform of the image display apparatus 100 according to the embodiment of the present invention may include OS based software in order to perform the above-described various operations.

First, referring to FIG. 4, the platform of the image display apparatus 100 according to an embodiment of the present invention is a separate type according to an exemplary embodiment of the present invention. The platform may be designed separately as a legacy system platform 400 and a smart system platform 405. An OS kernel 410 may be shared between the legacy system platform 400 and the smart system platform 405.

The legacy system platform 400 may include a driver 420, middleware 430, and an application layer 450 on the OS kernel 410. The smart system platform 405 may include a library 435, a framework 440, and an application layer 455 on the OS kernel 410.

The OS kernel 410 is a core of an operating system. When the image display apparatus 100 is driven, the OS kernel 410 may be responsible for at least one of hardware driver driving, security protection for hardware and processors in the image display apparatus 100, efficient management of system resources, memory management, hardware interfacing by hardware abstraction, multi-processing, and scheduling associated with the multi-processing.

The hardware drivers of the OS kernel 410 may include, for example, at least one of a display driver, a Wi-Fi driver, a Bluetooth driver, a USB driver, an audio driver, a power manager, a binder driver, and a memory driver.

The hardware drivers of the OS kernel 410 may be drivers for hardware devices within the OS kernel 410 and include a character device driver, a block device driver, and a network device driver. The block device driver may require a buffer for buffering data on a block basis, because data is transmitted on a block basis. The character device driver may not require a buffer since data is transmitted on a basic data unit basis, that is, on a character basis.

The OS kernel 410 may be implemented based on any of various OSs such as Unix (Linux), Windows, etc. The OS kernel 410 may be a general-purpose open OS kernel that can be implemented in other electronic devices.

The driver 420 is installed between the OS kernel 410 and the middleware 430. Along with the middleware 430, the driver 420 drives devices for operations of the application layer 450. For example, the driver 420 may include a driver(s) for a microcomputer, a display module, a graphics processing unit (GPU), the FRC, a General-Purpose Input/Output (GPIO) pin, a High-Definition Multimedia Interface (HDMI), a System Decoder (SDEC) or DEMUX, a Video Decoder (VDEC), an Audio Decoder (ADEC), a Personal Video Recorder (PVR), and/or an Inter-Integrated Circuit (I2C). These drivers operate in interaction with the hardware drivers of the OS kernel 410.

In addition, the driver 420 may further include a driver for the remote controller 200, especially a below-described 3D pointing device. The driver for the 3D pointing device may reside in the OS kernel 410 or the middleware 430, instead of the driver 420.

The middleware 430 is located between the OS kernel 410 and the application layer 450. The middleware 430 may mediate between different hardware devices or different software programs, for data transmission and reception between the hardware devices or software programs. Therefore, the middleware 430 can provide standard interfaces, support various environments, and enable interaction between tasks conforming to heterogeneous communication protocols.

Examples of the middleware 430 in the legacy system platform 400 may include Multimedia and Hypermedia information coding Experts Group (MHEG) and Advanced Common Application Platform (ACAP) as data broadcasting-related middleware, PSIP or SI middleware as broadcast information-related middleware, and Digital Living Network Alliance (DLNA) middleware as peripheral device communication-related middleware.

The application layer 450 that resides on the middleware 430 in the legacy system platform 400 may include, for example, UI applications associated with various menus in the image display apparatus 100. The application layer 450 that resides on the middleware 430 may allow editing and updating over a network by user selection. With use of the application layer 450, the user may enter a desired menu among various UIs by manipulating the remote controller 200 during viewing of a broadcast program.

The application layer 450 in the legacy system platform 400 may further include at least one of a TV guide application, a Bluetooth application, a reservation application, a Digital Video Recorder (DVR) application, and a hotkey application.

In the smart system platform 405, the library 435 is located between the OS kernel 410 and the framework 440, forming the basis of the framework 440. For example, the library 435 may include a Secure Socket Layer (SSL) being a security-related library, WebKit being a Web engine-related library, c library (libc), and Media Framework being a media-related library such as specifying a video format and an audio format. The library 435 may be written in C or C++. Additionally, the library 435 may be accessible to a developer through the framework 440.

The library 435 may include a runtime 437 with a core Java library and a Virtual Machine (VM). The runtime 437 and the library 435 form the basis of the framework 440.

The VM may be a virtual machine that enables concurrent execution of a plurality of instances, that is, multi-tasking. For each application of the application layer 455, a VM may be allocated and executed. For scheduling or interconnection between instances, the binder driver (not shown) of the OS kernel 410 may operate.

The binder driver and the runtime 437 may connect Java applications to C-based libraries.

The library 435 and the runtime 437 may correspond to the middleware 430 of the legacy system platform 400.

In the smart system platform 405, the framework 440 includes programs on which applications of the application layer 455 are based. The framework 440 is compatible with any application and may allow component reuse, movement or exchange. The framework 440 may include support programs and programs for interconnection of different software components. For example, the framework 440 may include a resource manager, an activity manager related to activities of applications, a notification manager, and a content provider (CP) for abstracting common information between applications. This framework 440 may be written in Java.

The application layer 455 on top of the framework 440 includes a variety of programs that are executed and displayed in the image display apparatus 100. The application layer 455 may include, for example, a core application that has at least one of an e-mail, Short Message Service (SMS), calendar, map, and browser. Function may be provided. The application layer 455 may be written in Java.

In the application layer 455, applications may be categorized into user-undeletable applications 465 stored in the image display apparatus 100 and user-installable or user-deletable applications 475 that are downloaded from an external device or a network and stored in the image display apparatus 100.

With the applications of the application layer 455, a variety of functions may be performed by network access, including Internet telephony, VoD, Web album, Social Networking Service (SNS), Location-Based Service (LBS), map service, Web browsing, and application search. In addition, the user may enjoy games and manage schedules using applications.

Referring to FIG. 5, a platform for the image display apparatus 100 according to another embodiment of the present invention is an integrated type platform. The integrated type platform may include an OS kernel 510, a driver 520, middleware 530, a framework 540, and an application layer 550.

Compared to the separate-type platform illustrated in FIG. 4, the integrated type platform of FIG. 5 is characterized by the absence of the library 435 and the application layer 550 being an integrated layer. The driver 520 and the framework 540 correspond to the driver 420 and the framework 440 of FIG. 4, respectively.

The library 435 of FIG. 4 may be incorporated into the middleware 530. That is, the middleware 530 may include both the legacy system middleware and the image display system middleware. As described above, the legacy system middleware includes MHEG or ACAP as data broadcasting-related middleware, PSIP or SI middleware as broadcast information-related middleware, and DLNA middleware as peripheral device communication-related middleware, whereas the image display system middleware includes SSL as a security-related library, WebKit as a Web engine-related library WebKit, libc, and Media Framework as a media-related library. The middleware 530 may further include the above-described runtime.

The application layer 550 may include menu-related applications, a TV guide application, a reservation application, etc. as legacy system applications, and e-mail, SMS, a calendar, a map, and a browser as image display system applications.

In the application layer 550, applications may be categorized into user-undeletable applications 565 that are stored in the image display apparatus 100 and user-installable or user-deletable applications 575 that are downloaded from an external device or a network and stored in the image display apparatus 100.

The platforms illustrated in FIGS. 4 and 5 may be general-purpose ones that can be implemented in many other electronic devices as well as in image display apparatuses.

The platforms illustrated in FIGS. 4 and 5 may be loaded on the memory 140, the controller 170, or any other processor (not shown).

FIG. 6A is a diagram showing an operating method using the first surface of the remote controller of FIG. 1B.

FIG. 6A shows the case in which the pointer 205 is displayed in correspondence with movement of the remote controller 200 in a state in which the first surface 201 of the remote controller 200 is upturned.

First, FIG. 6A(a) shows the case in which the pointer 205 is displayed in correspondence with the remote controller 200 at a predetermined position of the display 180.

The user may move the remote controller 200 up and down, side to side (FIG. 6A(b)), and back and forth (FIG. 6A(c)). The pointer 205 displayed on the display 180 of the image display apparatus moves in accordance with the movement of the remote controller 200. In this context, the remote controller 200 may be referred to as a pointing device or a 3D pointing device.

Referring to FIG. 6A(b), if the user moves the remote controller 200 to the left, the pointer 205 displayed on the display 180 of the image display apparatus moves to the left accordingly.

Information about the movement of the remote controller 200 sensed by the sensor of the remote controller 200 is transmitted to the image display apparatus. The image display apparatus 100 may calculate the coordinates of the pointer 205 from the information about the movement of the remote controller 200. Then, the image display apparatus 100 may display the pointer 205 at the calculated coordinates.

Referring to FIG. 6A(c), while pressing a predetermined button of the remote controller 200, the user moves the remote controller 200 away from the display 180. Then, a selection area corresponding to the pointer 205 may be zoomed in upon and enlarged on the display 180. On the contrary, if the user moves the remote controller 200 toward the display 180, the selection area corresponding to the pointer 205 is zoomed out and thus contracted on the display 180. Alternatively, when the remote controller 200 moves away from the display 180, the selection area may be zoomed out and when the remote controller 200 approaches the display 180, the selection area may be zoomed in on.

With the predetermined button pressed in the remote controller 200, the up, down, left and right movements of the remote controller 200 may be ignored. That is, when the remote controller 200 moves away from or approaches the display 180, only the back and forth movements of the remote controller 200 are sensed, while the up, down, left and right movements of the remote controller 200 are ignored. Unless the predetermined button is pressed in the remote controller 200, the pointer 205 moves in accordance with the up, down, left or right movement of the remote controller 200.

The speed and direction of the pointer 205 may correspond to the speed and direction of the remote controller 200.

After step 820 (S820) of FIG. 8, that is, after home screen display, the following steps may be performed.

The image display apparatus 100 determines whether dynamic screen display input is received (S825) and, if so, displays a dynamic screen (S830).

The image display apparatus 100 determines whether dynamic screen movement input is received in a state of displaying the dynamic screen (S835). If so, the dynamic screen may be moved and displayed (S840).

After step 830 (S830), the image display apparatus 100 determines whether dynamic screen enlargement input is received in a state of displaying the dynamic screen (S845). If so, the dynamic screen may be enlarged and displayed (S850).

In order to display the dynamic screen in a state of displaying the home screen, a PIP key 241 of the remote controller 200 may be manipulated.

The dynamic screen described in the present specification is a screen which may be actively moved on a display screen and may include, for example, a broadcast image screen or a widget screen. Hereinafter, the broadcast image screen will be focused upon as the dynamic screen.

For example, if the user who has viewed card objects 950, 970 and 990 wishes to view a live broadcast image on the home screen 901 on which the live broadcast image 910 is not displayed and then manipulates the PIP key 241 of the remote controller 200, the live broadcast image 1010 may be displayed as shown in FIG. 10A.

The live broadcast image 1010 may be a broadcast image of the same channel as the live broadcast image 910 displayed on a previous home screen 900 as shown in FIG. 9A. Then, the user can view a desired live broadcast image without switching the home screen.

The live broadcast image 1010 is preferably displayed in a region other than an important information display region on the displayed screen. For example, as shown in FIG. 10A, the live broadcast image 1010 is preferably displayed in a region other than a my interest card object 990 in which a content list automatically updated at a predetermined time interval is displayed.

Alternatively, the live broadcast image 1010 may be displayed to overlap a card object, the frequency of use of which is smallest, the number of times of use of which is smallest or the use time of which is smallest, among a plurality of card objects. That is, since the live broadcast image 1010 may be displayed to overlap a plurality of card objects having lowest importance, the user can view a content list, in which the user has interest, without interruption.

Alternatively, if the user arranges the pointer 205 in a region of the image display apparatus 100 using the remote controller 200, the live broadcast image 1010 may be arranged in the vicinity of that region.

Alternatively, if the user arranges the pointer 205 in a region of the image display apparatus 100 using the remote controller 200, since the user may have interest in that region, the live broadcast image 1010 may be arranged in a region other than that region.

FIG. 10A shows the case in which the live broadcast image 1010 is displayed to overlap the content list in a tube card object 950 if the PIP key 241 of the remote controller 200 is manipulated in a state in which the pointer 205 is displayed in the launcher bar area 903.

The live broadcast image 1010 displayed on the home screen may be displayed on the home screen in a state in which the live broadcast image is partially transparent. Accordingly, no region of the home screen is obscured.

Unlike the figure, the live broadcast image may be displayed between card objects or above card objects so as not to obscure the card objects of the home screen. The size of the displayed live broadcast image may be less than that of the live broadcast image of FIG. 10A. That is, the size of the live broadcast image may be changed according to the size of the empty space of the screen.

If 2D to 3D switching input is received in a state in which the live broadcast image 1010 of FIG. 10A is displayed on the home screen, the controller 170 of the image display apparatus 100 may switch the displayed image to a 3D image. Depths may be applied to objects such that the user perceives the objects as protruding. At this time, the depth of the live broadcast image may be set to be largest, such that the live broadcast image appears as protruding from the other objects.

FIG. 10B shows the case in which the pointer 205 displayed in correspondence with movement of the remote controller 200 is moved into the live broadcast image 1010 in a state in which the live broadcast image 1010 is displayed in the tube card object 950.

Then, an object 1020 for moving or enlarging the live broadcast image 1010 may be displayed. In FIG. 10B, the object 1020 is displayed to overlap the live broadcast image 1010. The object 1020 may be transparently displayed and thus the user can move or enlarge the live broadcast image while viewing the live broadcast image 1010.

Unlike FIG. 10B, the object 1020 for moving or enlarging the live broadcast image may be displayed so as to appear separated from the live broadcast image 1010. For example, the object 1020 for moving or enlarging the live broadcast image may be displayed in the vicinity of the pointer 205 displayed in correspondence with movement of the remote controller 200. Even in this case, the object 1020 for moving or enlarging the live broadcast image is transparently displayed so as not to obscure the other card objects.

In FIG. 10B, the object 101 includes a left upward movement item 1021, a right upward movement item 1022, a left downward movement item 1023, a right downward movement item 1024, an exit item 1025, a full view item 1026 and a screen enlargement item 1027.

FIG. 10C shows the case in which the left upward movement item 1021 of the object 1020 for moving or enlarging the live broadcast is selected. As shown in FIG. 10C, the live broadcast image 1010 is displayed in the left upper region of the home screen 901.

Next, if the screen enlargement item 1027 of the object 1020 for moving or enlarging the live broadcast shown in FIG. 10B is selected, the enlarged live broadcast image 1015 is displayed on the home screen 901 as shown in FIG. 10D. At this time, the screen enlargement item 1027 of the object 1020 may be changed to a screen reduction item 1028 as shown in FIG. 10D.

If the display region of the live broadcast image 1010 is determined according to a user point of gaze and the user point of gaze has interest in and is fixed to the full region of the home screen, display of the live broadcast image 1010 may be stopped.

Alternatively, if the user presses the PIP key 241 of the image display apparatus 200 once more, display of the live broadcast image 1010 may be stopped.

FIG. 10E shows the case in which, since the display of the live broadcast image has been stopped, the live broadcast image is not displayed on the home screen 901 and an icon 1017 for replaying the live broadcast image is displayed. The icon 1017 is preferably displayed in an empty region of the home screen.

Although the object, etc. is selected using the pointer 205 indicating movement of the remote controller 200 in FIGS. 9A to 10E, the present invention is not limited thereto and various modifications are possible.

For example, the object, etc. may be selected using the direction key and the OK key of the remote controller 200. As another example, the object, etc. may be selected according to a user gesture based on the image of the user captured using the camera 195. As another example, user voice may be recognized and the object, etc. may be selected based on the recognized voice.

The image display apparatus 100 may display a hand-shaped pointer 506 corresponding to the hand 505 of a user 1104 based on the image of the user captured using the camera 195. The image display apparatus 100 may perform operation corresponding to the user gesture.

For example, if the hand movement of the user 1104 corresponds to an upward movement gesture as shown in FIG. 10F in a state in which the live broadcast image 1010 is displayed in a left lower region of the home screen by the dynamic screen display input, the image display apparatus 100 may determine that the live broadcast image 1010 is moved up and may move the live broadcast image 1010 displayed in the left lower region to the left upper region as shown in FIG. 10F. At this time, the hand-shaped pointer 506 may be displayed on the moved live broadcast image 1010.

As another example, the remote controller 200 including a microphone (not shown) may receive and send user voice to the image display apparatus 100. If the user outputs voice 503 “Please move the dynamic screen to the left upper side” in a state of displaying the home screen as shown in FIG. 10G, the remote controller 200 may collect and send data of such voice 503 to the image display apparatus 100. The image display apparatus 100 may analyze user voice using a voice recognition function and recognize a command for moving the dynamic screen to the left upper side. Thus, as shown in FIG. 10G, the live broadcast image 1010 displayed in the left lower region may be moved to the left upper region.

The dynamic screen displayed on the image display apparatus may be transferred to and displayed on another electronic apparatus by a movement display command of the user.

If the user outputs voice 502 “Please transfer the dynamic screen to tablet” in a state of displaying the home screen as shown in FIG. 10H, the remote controller 200 may collect and send data of such voice 502 to the image display apparatus 100. The image display apparatus 100 may analyze user voice using a voice recognition function and recognize a command to transfer the dynamic screen to the tablet.

For movement and display, first, the image display apparatus 100 performs pairing with the tablet and then sends a network address to the tablet via the network interface 130, if the displayed live broadcast image is received over a network. Then, the tablet may display the live broadcast image 1011 as shown in FIG. 10H.

If the live broadcast image displayed on the image display apparatus 100 is received through the tuner unit 110, the image display apparatus 100 converts the live broadcast image into a stream and sends the converted stream to the tablet via the network interface 130. Then, the tablet may display the live broadcast image 1011 as shown in FIG. 10H.

The command for selecting the image display apparatus may be input through the direction key and the OK key, the user gesture, user voice, etc. in addition to the pointer of the remote controller. Hereinafter, although the pointer indicating movement of the remote controller is focused upon, a direction key and an OK key, a user gesture, user voice, etc. may be used as described above.

FIGS. 11A to 11E are similar to FIGS. 10A to 10E in that the dynamic screen is displayed on the home screen, but are different therefrom in that a live broadcast card object 920 is displayed on the screen 900.

FIG. 11A shows the case in which a live broadcast image 1110 is displayed on the home screen 900 to be separated from the live broadcast card object 920 if the PIP key 241 of the remote controller 200 is manipulated in a state in which the home screen 900 is displayed.

At this time, the object 1020 for moving or enlarging the live broadcast image may be displayed in the region in which the live broadcast image has been displayed in the live broadcast card object 920. FIG. 11A shows the case in which the right upward movement item 1022 of the object 1020 is selected and the live broadcast image 1110 is moved to and displayed in the right upper region of the home screen 900. At this time, the live broadcast image 1110 may be a broadcast image of the same channel as the live broadcast image displayed in the live broadcast card object 920.

FIG. 11B shows the case in which the right downward movement item 1024 of the object 1020 for moving or enlarging the live broadcast image is selected. Then, as shown in FIG. 11B, the live broadcast image 1110 is arranged and displayed in the right lower region of the home screen 900. In FIG. 11B, the live broadcast image 1110 is displayed to partially overlap a 3D card object 960 and an application list 980.

FIG. 11C shows the case in which the left upward movement item 1021 of the object 1020 for moving or enlarging the live broadcast image is selected. Then, as shown in FIG. 11C, the live broadcast image 1110 is arranged and displayed in the left upper region of the home screen 900. At this time, the live broadcast image 1110 is displayed to partially overlap the object 1020 for moving or enlarging the live broadcast image. In this case, at least one of the live broadcast image 1110 or the object 1020 may be transparently displayed so as not to obscure each other.

FIG. 11D shows the case in which the left downward movement item 1023 of the object 1020 for moving or enlarging the live broadcast image is selected. Then, as shown in FIG. 11D, the live broadcast image 1110 is arranged and displayed in the left lower region of the home screen 900.

FIG. 11E shows the case in which the screen enlargement item 1027 of the object 1020 for moving or enlarging the live broadcast image is selected. Then, as shown in FIG. 11E, the enlarged live broadcast image 1115 is displayed on the home screen 900. At this time, the screen enlargement item 1027 of the object 1020 may be changed to a screen reduction item 1028 as shown in FIG. 11E.

If the PIP key 241 of the remote controller 200 is manipulated in a state in which the live broadcast image is displayed in the live broadcast card object 920, a live broadcast image different from the displayed live broadcast image may be additionally displayed. The additionally displayed live broadcast image may be a broadcast image of a channel different from that of the displayed broadcast image.

FIGS. 10A to 11E show movement and enlargement of the displayed live broadcast image 1010 or 1110. Upon image movement or enlargement, unlike FIGS. 10A to 11E, as described above, if an updated card object is present, the image is moved to or enlarged in a region other than the updated card object, in a region other than a card object, the frequency of use of which is largest, the number of times of use of which is largest or the use time of which is largest, or in a region other than a region in which the pointer is displayed.

For example, in FIG. 10B, even when the right upward movement item 1022 is selected, the live broadcast image is not displayed in an updated card object of interest 990 but is preferably displayed in a smart share card object 970. Therefore, the user can view an important information region even when the live broadcast image is displayed.

FIG. 12 shows the case in which a separate live broadcast image 1210 different from a live broadcast image of Channel 5 in the live broadcast card object 920 is displayed if the PIP key 241 of the remote controller 200 is manipulated in a state in which the live broadcast image is displayed in the live broadcast card object 920.

At this time, an object 1220 for moving or enlarging the live broadcast image 1210 may be displayed. Although the object 1220 is displayed to overlap the live broadcast image 1210 in FIG. 12, the object 1220 may be displayed so as to appear separated from the live broadcast image 1210.

If the live broadcast image 1210 and the object 1220 for moving or enlarging the live broadcast image overlap, one of the live broadcast image 1210 and the object 1220 may be transparently displayed.

In order to receive live broadcast images of a plurality of channels, a plurality of tuners is required. However, the live broadcast image of one channel may be received using one tuner and the live broadcast image of another channel may be received via the network interface 135.

The image of the user may be captured using the camera 195, the user point of gaze of the captured image of the user may be recognized and then the live broadcast image 1010 may be arranged in a region other than a region corresponding to the user point of gaze. Since the user focuses upon information displayed in the region corresponding to the user point of gaze, the live broadcast image 1010 may be displayed in the region other than the region corresponding to the user point of gaze.

The live broadcast image 1010 may float so as to be moved and displayed in correspondence with movement of the user point of gaze.

Although, when the PIP key 241 of the remote controller 200 is manipulated once, the live broadcast image 1210 different from the live broadcast image of Channel 5 in the live broadcast card object 920 is displayed in FIG. 12, another live broadcast image may be displayed if the PIP key 241 of the remote controller 200 is manipulated twice. In this case, the size of the first displayed live broadcast image 1210 may be less than that of the newly displayed live broadcast image. The size of the first displayed live broadcast image 1210 may be sequentially reduced. The icon 1017 for replaying the live broadcast image shown in FIG. 10E may also be displayed. Therefore, the user may further focus on the newly displayed live broadcast image.

FIG. 13 shows the case in which the user point of gaze is recognized using the camera 195 in a state in which the home screen 901 is displayed. The controller 170 may calculate the face movement direction and the pupil movement direction of the user 1300 from the captured image of the user and estimate the user point of gaze.

If the user point of gaze is estimated, the live broadcast image 1010 may be displayed in a region other than the region 1302 corresponding to the user point of gaze. In FIG. 13, the user point of gaze corresponds to the right side of the image display apparatus and the live broadcast image 1010 is displayed on the left side of the image display apparatus. Therefore, the live broadcast image 1010 may be displayed without interrupting the user viewing experience.

At this time, the object 1220 for moving or enlarging the live broadcast image may be displayed to overlap the live broadcast image 1010 and one of the live broadcast image 1010 and the object 1020 for moving or enlarging the live broadcast image may be transparently displayed.

FIG. 14A shows the case in which the application full view item 983 of the application list is selected based on the pointer 205 displayed in correspondence with movement of the remote controller 200 in a state in which the live broadcast image 1410 is displayed on the home screen 901.

Thus, as shown in FIG. 14B, an application list screen 1405 including a plurality of application items may be displayed on the image display apparatus 100 as a full screen. The location and size of the live broadcast image 1410 displayed at this time may be equal to those of the live broadcast image displayed on the home screen 901.

As shown in FIG. 14C, the size of a live broadcast image 1415 displayed on the application list screen 1405 may be greater than that of the live broadcast image shown in FIG. 14A. In addition, the display location of the live broadcast image may be changed.

Since the amount of information displayed on the home screen 901 of FIG. 14A is large, the size of the live broadcast image is small. However, since the amount of information displayed on the application list screen 1405 of FIG. 14C is small, that is, since an empty space is large, the live broadcast image 1315 may be enlarged and displayed. Therefore, the live broadcast image 1315 is more easily viewed.

FIG. 15 is a flowchart illustrating a method for operating an image display apparatus according to an embodiment of the present invention, and FIGS. 16A to 18E are views referred to for describing various examples of the method for operating the image display apparatus of FIG. 15.

Referring to FIG. 15, the image display apparatus 100 displays the home screen (S1520).

Step 1520 (S1520) of displaying the home screen is equal to step 820 (S820) of displaying the home screen and thus a description thereof will be omitted.

FIG. 16A shows an example of the home screen 900 of the image display apparatus.

FIG. 16B shows another example of card objects. In FIG. 16A, if a screen switch object 935 is selected to switch the screen, a home screen 901 for displaying a tube card object 950, a smart share card object 970 or a my interest card object 990 may be displayed in the dashboard area 902.

After step 1520 (S1520) of FIG. 15, that is, after home screen display, the following steps may be performed. That is, the image display apparatus 100 determines whether an object for switching a content list of a first card object displayed on the home screen is selected (S1530) and, if so, displays a second content list corresponding to a second subcategory in the first card object based on a first subcategory among a plurality of subcategories (S1540).

FIG. 16B shows the case in which a content list 975 a including new content items is displayed in the smart share card object 970. At this time, an object 974 for switching a content list may be displayed as “¼” as shown in FIG. 16B. This may mean that a first content list among four content lists is displayed.

Next, if the object 974 for switching the content list is selected once using the pointer 205 displayed in correspondence with movement of the remote controller 200, the controller 170 may control display of a content list 975 b including movie content items in the smart share card object 970 as shown in FIG. 16C. At this time, an object 976 for switching the content list may be displayed as “ 2/4” as shown in FIG. 16C. This may mean that a second content list among four content lists is displayed.

The content lists displayed in the other card objects located near the smart share card object 970 may not be changed. That is, as shown in FIG. 16C, a content list 955 a including recently featured items may be displayed in the tube card object 950 without change and a content list 995 a including world news items may be displayed in the my interest card object 990 without change.

Next, if the object 974 for switching the content list is selected twice more as compared to FIG. 16A, that is, if the object 974 for switching the content list is selected once more as compared to FIG. 16B, the controller 170 may control display of a content list 975 c including photo content items in the smart share card object 970 as shown in FIG. 16D. At this time, an object 977 for switching the content list may be displayed as “¾” as shown in FIG. 16D. This may mean that a third content list among four content lists is displayed.

The content lists displayed in the other card objects located near the smart share card object 970 may not be changed. That is, as shown in FIG. 16D, a content list 955 a including recently featured items may be displayed in the tube card object 950 without change and a content list 995 a including world news items may be displayed in the my interest card object 990 without change.

Next, if the object 974 for switching the content list is selected three times more as compared to FIG. 16A, that is, if the object 974 for switching the content list is selected once more as compared to FIG. 16C, the controller 170 may control display of a content list 975 d including photo content items in the smart share card object 970 as shown in FIG. 16E. At this time, an object 978 for switching the content list may be displayed as “ 4/4” as shown in FIG. 16E. This may mean that a fourth content list among four content lists is displayed.

The content lists displayed in the other card objects located near the smart share card object 970 may not be changed. That is, as shown in FIG. 16E, a content list 955 a including recently featured items may be displayed in the tube card object 950 without change and a content list 995 a including world news items may be displayed in the my interest card object 990 without change.

Although the object, etc. is selected using the pointer 205 indicating movement of the remote controller 200 in FIGS. 16A to 16E, the present invention is not limited thereto and various modifications are possible.

For example, the object, etc. may be selected using the direction key and the OK key of the remote controller 200. As another example, the object, etc. may be selected according to a user gesture based on the image of the user captured using the camera 195. As another example, user voice may be recognized and the object, etc. may be selected based on the recognized voice.

For example, the image display apparatus 100 may display a hand-shaped pointer 506 corresponding to the hand 505 of a user 1104 based on the image of the user captured using the camera 195. In a state of displaying the home screen shown in FIG. 16D, if hand movement of the user 1104 corresponds to a tap gesture for selecting the object 977 for switching the content list, it may be determined that the object is selected. Therefore, as shown in FIG. 16F, the content list 975 d including music content items may be displayed in the smart share card object 970. At this time, the hand-shaped pointer 506 may be displayed on an object 978 for switching the content list “4/4”.

As another example, the remote controller 200 including a microphone (not shown) may receive and send user voice to the image display apparatus 100. If the user outputs voice 507 “Show me the fourth list of smart share” in a state of displaying the home screen as shown in FIG. 16D, the remote controller 200 may collect and send data of such voice 507 to the image display apparatus 100. The image display apparatus 100 may analyze user voice using a voice recognition function and recognize a command for displaying the content list. Thus, as shown in FIG. 16F, the content list 975 d including the music content item may be displayed in the smart share card object 970.

The command for selecting the image display apparatus may be input through the direction key and the OK key, the user gesture, user voice, etc. in addition to the pointer of the remote controller. Hereinafter, although the pointer indicating movement of the remote controller is focused upon, the direction key and the OK key, the user gesture, user voice, etc. may be used as described above.

FIGS. 16H to 16J show detailed examples of the smart share card object 970 of the home screen 901 shown in FIG. 16B.

In FIG. 16H, the smart share card object 970 further includes a settings object 981. If a card object name 972 is selected using the pointer 205, a smart share screen 973 a shown in FIG. 16I may be displayed on the image display apparatus.

The shared content according to the embodiment of the present invention may include not only content stored in an electronic apparatus connected to the image display apparatus via a home network but also other content. For example, content stored in an external server may be shared over a network. More specifically, if a first user logs in to the image display apparatus 100, not only content stored in an electronic apparatus connected to the image display apparatus over a home network but also content stored in an external server by the first user may be shared in smart share card object 970 or on the smart share screen 973 a. At this time, a process of logging in to the external server may be required. Alternatively, when the user logs in to the image display apparatus 100, the user may automatically log in to the external server. Therefore, a content sharing function may be further activated.

A content list 971 a of the home network and a content list 971 b of the external network are separately displayed on the smart share screen 973 a of FIG. 16I. FIG. 16I shows the case in which the user logs in to the image display apparatus using the camera 195 and an icon 1114 indicating the user 1104 is displayed on the smart share screen 973 a.

The settings object 981 may be displayed on the smart share screen 973 a. Various settings may be performed using the settings object 981. For example, shared content may be set to be restricted to the home network or to extend to the external network. As another example, shared content may be set to be displayed on a per user basis or all shared content may be set to be displayed regardless of users. Alternatively, shared content may be set to be displayed on a per age basis. Alternatively, while shared content is displayed, a lock function for certain content may be set to be activated. Alternatively, subcategories other than new, movie, photo and music may be further set. Alternatively, only newly added content may be set to be displayed as newly shared content settings. A period of synchronization with the home network may be set. Upon shared content update, a time when a content list is displayed may be set. For example, if a new content list is received over the home network, the new content list may be immediately displayed. Alternatively, a content list to be displayed may be updated at a predetermined time interval and a new content list may be displayed upon update.

FIG. 16J shows a smart share screen 973 b different from that of FIG. 16I. The smart share screen 973 b of FIG. 16J includes a list 971 c of electronic apparatuses connected to the image display apparatus 100 and a list 971 d of electronic apparatuses which are not connected to the image display apparatus 100 among the electronic apparatuses included in the home network. Unlike the figure, the lists 971 c and 971 d are separately displayed on the screen.

In the figure, a refrigerator item, a laptop item and a home server item are included in the list 971 c of electronic apparatuses connected to the image display apparatus 100 and a tablet item, a computer item and a washing machine item are included in the list 971 d of electronic apparatuses which are not connected to the image display apparatus 100.

If the computer item is selected from the list 971 d of electronic apparatuses that are not connected to the image display apparatus 100, a separate menu may be displayed and thus a remote power-on operation of the computer may be performed.

A card object corresponding to the smart share screen 973 b shown in FIG. 16I may be displayed on the home screen. Therefore, it is possible to easily confirm electronic apparatuses connected to the image display apparatus 100 and electronic apparatuses which are not connected to the image display apparatus 100.

FIGS. 17A to 17E are similar to FIGS. 16A to 16E and are different therefrom in that the content list of the smart share card object 970 is not changed but the content of the tube card object 950 is changed.

FIG. 17A shows a home screen 900 equal to that of FIG. 16A. If the screen switching object 935 is selected based on the pointer 205 displayed in correspondence with movement of the remote controller 200, as shown in FIG. 17B, a home screen 901 for displaying the tube card object 950, the smart share card object 970 and a my interest card object 990 may be displayed in the dashboard area 902.

FIG. 17B shows the case in which a content list 955 a including recently featured items is displayed in the tube card object 950. At this time, an object 954 for switching a content list may be displayed as “¼” as shown in FIG. 17B. This may mean that a first content list among four content lists is displayed.

Next, if the object 954 for switching the content list is selected once using the pointer 205 displayed in correspondence with movement of the remote controller 200, the controller 170 may control display of a content list 955 b including most viewed items in the tube card object 950 as shown in FIG. 17C. At this time, an object 956 for switching the content list may be displayed as “ 2/4” as shown in FIG. 17C. This may mean that a second content list among four content lists is displayed.

The content lists displayed in the other card objects located near the tube card object 950 may also be changed. That is, as shown in FIG. 17C, a content list 975 b including movie content items may be displayed in the smart share card object 970 and a content list 995 b including top stories news items may be displayed in the my interest card object 990.

Next, if the object 954 for switching the content list is selected twice more as compared to FIG. 17A, that is, if the object 956 for switching the content list is selected once more as compared to FIG. 17B, the controller 170 may control display of a content list 955 c including trending video items in the tube card object 950 as shown in FIG. 17D. At this time, an object 957 for switching the content list may be displayed as “¾” as shown in FIG. 1 dc. This may mean that a third content list among four content lists is displayed.

The content lists displayed in the other card objects located near the tube card object 950 may also be changed. That is, as shown in FIG. 17D, a content list 975 c including photo content items may be displayed in the smart share card object 970 and a content list 995 c including business news items may be displayed in the my interest card object 990.

Next, if the object 954 for switching the content list is selected three times more as compared to FIG. 17A, that is, if the object 957 for switching the content list is selected once more as compared to FIG. 17C, the controller 170 may control display of a content list 955 d including 3D content items in the tube card object 950 as shown in FIG. 17E.
